Nitric oxide is the compound your circulation relies on — and these two amino acids are what your body uses to make it.

Halea Life L-Citrulline and L-Arginine Performance Capsules deliver a targeted blend of L-Citrulline DL-Malate, L-Arginine HCl, and L-Arginine Alpha-Ketoglutarate — the direct precursors to nitric oxide synthesis. Designed to support healthy blood flow, oxygen delivery, and vascular performance. No stimulants. No fillers. Just the amino acids your body's nitric oxide pathway requires.*

Who this is for:
Active adults and athletes looking to support vasodilation, blood flow, and oxygen and nutrient delivery to working muscles. Useful pre-workout for performance and pump, or daily for people who want ongoing cardiovascular and circulatory support. Also popular with adults over 40, for whom natural nitric oxide production begins to decline with age.*

How the ingredients work together:
L-Citrulline DL-Malate is the preferred citrulline form for performance — DL-Malate enhances absorption and adds malic acid's role in the Krebs cycle for additional ATP support. Citrulline is converted to arginine in the kidneys more efficiently than supplemental arginine alone, making it the more effective nitric oxide precursor for sustained vascular support. L-Arginine HCl is the direct substrate for nitric oxide synthase (NOS) — the enzyme that produces nitric oxide from arginine in vascular endothelial cells. L-Arginine Alpha-Ketoglutarate (AAKG) enhances arginine's bioavailability and adds the metabolic benefits of alpha-ketoglutarate, a Krebs cycle intermediate that supports energy metabolism and recovery. Together, these three forms create a comprehensive nitric oxide support stack — addressing both the upstream conversion pathway (citrulline) and the direct substrate supply (arginine).*

Stimulant-free performance support:
Unlike many pre-workout formulas, this blend contains no caffeine, no beta-alanine, and no stimulants — making it suitable for evening training, sensitive individuals, or stacking with existing pre-workout routines.
